Abstract

Dynamics of water passing through a 90 degrees horizontal bend of 90 degrees is examined in the context of core catcher as a part of nuclear reactor. In this study, the dynamics is simulated using Moving Particle Semi-Implicit method. The simulation results are then compared to the experiments. The simulation results show that the water depth patterns obtained in this study are similar to experiment results. In addition, the travel time of water agrees with the experimental results. This shows the capability of Moving Particle Semi-Implicit method as an alternative numerical method for liquid transport.
